What You Need to Know about Commercial and Residential Roofing
There are key differences between a residential and a commercial roofing even if they serve the same purpose, and so take note that the first question a roofing contractor will ask you is if you are in need of a residential or a commercial roofing job. Be aware that the differences between a commercial and a residential roofing project are very much different, from the design, structural elements, to the materials and costs.
The first thing to mention is the size difference in constructing a commercial roof from that of a residential roof and thus the structural needs differ. Imagine for example the size of the roof of your house compared to the size of the roof of department store, where the load requirements, fixtures and materials will definitely vary. The commercial roof for instance has to have a larger load bearing capacity than a residential roof because of the materials needed in the construction. In the same manner that you would need more number of crew when installing a commercial roof because it is a bigger job compared to a residential roof.
Compared to a residential roofing, commercial roofs have the tendency to have more protrusions with regards to the function of the roof. A residential roof may need to accommodate protrusions like chimneys, skylights and others, a commercial roofing will have to consider others like ventilation systems, smoke stacks, pipes, roof entrances and other mechanical needs. Depending on the needs, there could be some special construction specifications that could occur for a commercial and residential roofing. One reason is the function of the building, as for instance, if a commercial roofing is for an establishment meant for heavy machinery, then its roofing must be able to withstand heat discharge. Likewise, the construction of a residential roofing could also be based on the purpose of the homeowners, from its appearance, durability and maintenance.
With the size and scope of the project for either commercial or residential, you have to consider too the specialized knowledge and skills of your potential roofers. The function of the commercial building has to be taken into account by the commercial roofers while the residential roofers have to take into account the unique needs of their clients.
Because of the various conditions of the two roofing contractors, they will in turn have different needs to complete their jobs. Of the two contractors, the commercial roofing contractor is viewed to be more difficult and more involved in the job because of the scope of the job, and in turn affecting the fact that it is difficult to find skilled workers and the number of this skilled people, which in turn would affect the cost they will give you of the project.
